Mobile network operator 3 has scrapped roaming charges for its UK customers in seven countries.

Its users will no longer be charged extra for making or receiving calls or texts when visiting the Republic of Ireland, Italy, Austria, Sweden, Denmark Hong Kong and Australia where it own its own network, nor will there be any one-off fees to the access services.

It said calls back to the UK would be charged at the user’s same domestic rate and come under the user's usual monthly call allowance. Once the monthly allowance has been exceeded a flat rate of 20p per minute will apply.

If a user exceeds his or her monthly call allowance when phoning from one of the seven nations they will then be charged a flat fee of 20p a minute.

The company also backed the European Commission efforts, headed by Commissioner Viviane Reding, to enforce roaming-fee caps on operators. In November, she berated the industry’s "excessively high" roaming charges.

3 has a customer base of 13.5 million, of which 3.75 are in the UK.
